Macro-models for shear transfer in the reinforced concrete beam-column joints with headed anchorage of beam rebars are proposed. The models consist of the truss model and the strut model that fulfill the equilibrium of shear, moment and axial stresses. A criterion for the slip along the shear crack is also taken account to express the cone shaped splitting failure at the anchored portion. The results of the analysis varied concrete strength, amount of the transverse reinforcement and embedded length gave good agreement with the values of existing test results. The analytical results suggest that the tensile strength of the longitudinal bars in mid-depth of the column and the subjected axial load would contribute to the capacity of the joint shear transfer.
